CIRCUIT-CONTROLLER.

Application area December 20, 1910. Serial No. 598,307.

To all whomitmcy concern:

Beit known that I, JOHN P. CoLnMAN, a citizen ofthe United States, residing in the borou h of Manhattan, in the county of New ork and State of New York, have invented certain new and useful Improvements in Circuit-Controllers, of which the following is .a specification.

-My invention relates to circuit controllers, and has for an object the provision of a plurality of contact'fingers arranged in a compact form. I preferably mount the contact fingersradially in a circular contact carrier, and provide means at the 51'5" center for operating the said fingers.

I .will first describe one form of circuit controller embodying my invention, with a means for operating the contact fingers thereof, and then point out the novel features thereof in claims.

In the accompanyingdrawings, Figure 1 -is a. view showing in elevation, partly secanti operating these fingers. 5 are-views showing in detail the constructioned, a circuit controller in the form of a rela. and embodying my invention. Fig. 2

1s 4 new showing one set of the contact finer's-"of'the relay shown in Fig. 1, and showmore clearly the means for mounting Figs. 3, 4 and tion' of the contact-fingers shown in the precedingviews, Fig. 5 being a sectional view .on the; line VV of Fig. 3. Fig. 6/ is a view showing in perspective a means for mounting the contact fingers shown in the preceding views. Figs. 7 and 8 are views showing a means for applying an electromagnetic motor device to a circuit controller embodying my invention for operating the contact fingers thereof, Fig. 8 being a secformity v I obtain I by bringing tional view on the line VIII-VIII of Fi 7. p p

gimilar reference characters refer to similar parts throughout the several views.

One feature of my invention is the concentration of all the contacts within the smallest possible area, thereby facilitating the simultaneous observation of their operation. 1

Another feature of my invention is a high degree of uniformity of operation of all contacts by a common means, winch unithe point of action of all contacts as near as possible to a common point.

Still another feature of my invention is an arrangement of contacting devices to occupy a minimum amount of space, with a maximum of elect-rical separation between them.

A-further: feature is a construction which Specification ofLetters Patent. Patented Sept. 12, 1911. I

permits of changes in the functional operation of the contacting devices by mere. transposltlon of parts.

Referring now to Figs. 1 and 2, 8 designates.-

a circular contact carrier, preferably of insulatmg material such as porcelain, suitably mounted upon a base-12. Mounted in the contact carrier 8 to project radially toward the center are a plurality of contact fingers, here shown as being arranged in pairs, each pair consisting of a stationary finger 10 and a movable finger 9. At the cent-er of the contact carrier is a rotatable drum 11 preferably of insulating material. having means, here shownas slots 13, (see Fig. 2), for engaging with the movable contact finger 9 of each pair, to move this finger into and out of engagement with its'corresponding stationary finger 10. The drum 11 maybe rotated through a small arc of'a circle by any suitable means, as will be explained hereinafter. The contact fingers '9 and 10 are preferably mounted in the circular carrier 8 in such manner that any one of these fingers may be readily removed therefrom without disturbing the rest of the device. To accomplish this purpose, I may secure each finger to a jaw or stirrup 18 which is held in position against the circular carrier 8 by means of a square head 15 of a bolt 14:. Each stirrup 18 is provided with a slot 40 to accommodate the body of the bolt 14. The stirrup. is prevented from turning by resting against an inwardly projecting shoulder 19 of the carrier 18. The bolts l tarel'ield securely in. place by means of nuts 17, which nuts also serve to retain wires for electrical connections to the contact fingers. It will be evident from theforegoing description that a contact finger may be removed from the carrier 8 by loosening the nuts 17 and sliding the stirrup 18 out from under thehead 15 of the bolt 14.

As illustrated in Figs. 2, 3, 4 and 5, one con- This block 21 may be secured to the finger in any suitable manner, as for example, by means of a cup-shaped piece of copper 22 riveted to the finger as shown in Fig. 5. It will be evident -from Figs. 1 and 2 and the foregoing description that by rotating the drum 11 through a small arc of 'a circle in the direction indicated by the arrow, the contact fingers 10 will be moved into engagement with contact fingers 9; and that these fingers will be disengaged by a simi-. lar rotation of the drum 11 in the opposite direction.

Referring now to Figs. 7 and 8, I have shown a means for rotating the'drum 11 by an electro-magnetic motor device. This device as here shown is an alternating current induction motor, but I do not wish to be limited to this specific means. 23 designates a housing secured to one side of the circular carrier 8 by means of screws 25. These screws also serve to hold in position on the opposite side of the carrier 8 a plate 34: in which is pivoted one end of a shaft 33 carrying the drum 11. The other end of this shaft is pivoted in themotor frame as shown. 26 designates an induction motor, to the rotor of which is secured a pinion 27 This pinion drives a segmental gear 28 which is rigidly secured to a shaft 29. This shaft 29 carries a crank 30 which is operatively connected by means of a link 31 with a similar crank 32 secured to the drum shaft 33. It will be seen therefore that the rotation of the mgtor pinion 27 may be transmitted to the limited by means of suitable stops, suclrfor.

example as screws 35 and 36in the motor housing.

Although'in the arrangement illustrated in the drawings all of the pairs of .contact fingers 9 and 10 are disengaged when the electric motor device 26 is deenergized, and

device is energized, I do not wish to limit myself to this specific arrangement, for the arrangement may equally Well be suchthat certain pairs of contact fingers are normally in engagement, and are moved out of engagement when the motor device is energized.

Various other changes maybe made in the I f arrangement and structure of the parts of the relay within the scope ofthe appended claims Without departing from the spirit and scope of my invention.
